Flametongue gives you an additional amount of spell power and increases the off-hand damage on Lava Lash by 25%. Considering Lava Lash isn't a very powerful attack to begin with, 25% extra doesn't do a whole lot. The additional spell power is nice for the occasional Maelstrom LB or CL, but with Windfury on your off-hand, your Lava Lash becomes quite powerful as it gives Windfury a chance to proc on your off-hand outside of regular auto-attacks.
Basically, Lava Lash becomes a 125% off-hand attack or 20% chance of proccing Windfury on your off-hand (which hits for considerably more than Lava Lash with Flametongue) every 6 seconds. I don't know if off-hand can still clip main-hand Windfury attacks, but if that's the case you might want to go WF/FT with fast weapons and WF/WF with slow weapons.
I'm rolling with WF/WF on heirloom maces (2.8 speed, I think) and stuff just dies.
I'd like to correct you here in that "the occasional Maelstrom LB or CL" is really about once every 5-7 seconds.
And from reading EJ it seems that if you have WF on your main hand you have a 20% chance of proccing it outside the 3sec ICD, with WF on both weapons this rises to 36% per attack.
So not only is the second windfury less effective but Flametongue also adds an extra few hundred damage to lava lash and the spellpower enhances your shocks, static shock procs, magma totem damage and Maelstrom LB's/CL's.
All in all I'd say that 40-50% of an enhancement shaman's dps is from spells.
And I'm purely talking endgame here.
